After the Trades Council's rally from the late morning, the Strummers music club has organized its own celebration of International Workers' Day and of the continuing resistance to Conservative austerity cuts. The singer and guitarist Roy Bailey (last studio album Below the Radar) will perform from 4 to 6 p.m., and after a break the folk-punk band Eva's Dream, then the folk singer and bandleader Jez Hellard (Heavy Wood), will perform in support from 8 p.m. Tickets are £8, or £6 as concessions: we can write to Strummers or call 07903 521412 to book.

Tomorrow our friends from the Cambridge and District Trades Council will hold their annual Winter Warmer at the Portland Arms, with Attila the Stockbroker, Grace Petrie, and the other performers above, speakers from the Labour Party and from Lesbians and Gays Support the Migrants, and the poet and Peterborough Trades Council president Ron Graves as compère.

Last weekend Cambridge contributed six vehicles, carrying just under thirty people and over three thousand pounds' worth of aid, to the 250-vehicle Convoy to Calais in protest at the treatment of refugees by European governments. (In the event the convoy was refused entry by the French authorities: see the People's Assembly's report.) This weekend the Strummers music club has organized a concert to mark Refugee Week, and to say once again that refugees should be welcome in Britain.

The Strummers music club hosts the songwriter, activist, and performer Grace Petrie (latest album Whatever's Left) at the CB2 Bistro on Saturday, with support from the musicians of Cambridge Acoustic Nights. Tickets are £8 on the door, or £6 as concessions (contact Les Ray).

Musicians across the country are performing over two hundred gigs this weekend under the label We Shall Overcome to demonstrate solidarity with, and offer practical help to, those affected by austerity policies. The musicians won't take fees, and money raised by collections or ticket sales will go instead to the charitable shelters, soup kitchens, and food banks to which so many more have been driven in the last five years as welfare provision and public services have been withdrawn.

In the week that Greece's Syriza government has returned to the negotiating table and its people to the streets, the Cambridge Greece Solidarity Campaign and the Cambridge People's Assembly will hold an informal free concert in solidarity with the Greek people's struggle to break with the austerity policies that are crushing their country.

We present a new version of the song 'El pueblo unido jamás será vencido', recorded during an interview with members of the Cambridge People's Assembly broadcast on the Rebel Arts Radio programme on 15 June. The performers were Olivier (voice), David (guitar), and a nameless friend (violin). Olivier wrote the new English words, below, to the song originally written by Sergio Ortega and Quilapayún.

We present a video posted on our former blog in June 2014.
